Bridge USDC to Arc
Circle stopped issuing signatures for Arc around 2026-08-03. Transfers from every source chain are affected — they burn and then sit unsigned. We paused new transfers rather than take deposits we can't deliver. Funds already sent are not lost: the signature never expires and we're tracking every stuck transfer.
This is not specific to us or to one source chain: we tested burns from several chains, in both speeds, and none were signed, while the same chains bridging anywhere else were signed within minutes.
Already sent one? Use the recovery box below — it still works, and it will give you the message ID that Circle needs in order to release the funds.
Fast pays Circle a small fee (about 0.3 bps) and skips the finality wait, so it's the default. During the current outage neither speed is being signed — Fast is simply the one Circle still accepts for reprocessing.
Arc charges gas in USDC, so receiving on Arc costs gas you don't have yet when you arrive. We pay it for you. The recipient is signed into Circle's message, so the funds can only ever land in your wallet — we can't redirect or hold them, and if our relayer fails you can complete the transfer yourself later.
Sent a transfer that never arrived?
It isn't lost. Circle's signature for your transfer doesn't expire, so the delivery can be completed at any time. Paste the transaction hash from the chain you sent from and we'll finish it and pay the gas.
